What is shop-research?

A product-research workflow that searches Amazon, Google Shopping, and relevant specialist websites using a browser. It collects candidate details and screenshots, then creates an HTML report.

Use it to research gifts, gadgets, gear, home goods, or other products based on criteria you provide. It can rank a limited set of candidates and use feedback from earlier recommendations.

It reduces the need to compare products manually across several shopping sites. It also keeps the findings and selection criteria together in one report.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00138	$0.05242
Opus 5	$0.00069	$0.02621
Sonnet 5	$0.00028	$0.01048
Haiku 4.5	$0.00014	$0.00524

Measured 11d ago against content hash 7fa9828bec74, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade A, and why

shop-research scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 448 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Preferences

On startup, use Read to load ~/.claude/skills/shop-research/preferences.md. If missing, treat as first-run (see First-time detection below).

Defaults when no preferences exist:

output-root: ~/Desktop/shop-research/ (confirmed on first run)
default-sites: amazon, google-shopping
max-candidates: 5
currency: USD
tone: friendly-cli (terse, direct, warm — not corporate)
open-report: true (auto-open the HTML report when done)

Also load ~/.claude/skills/shop-research/feedback-journal.md if present — it contains thumbs-up/down on past recommendations. Summarize its signal (e.g., "prefers minimal aesthetic", "avoids fast-fashion brands") and carry that into ranking.

Context

On startup, use Bash to detect: today's date (date +%Y-%m-%d), and whether ~/Desktop/shop-research/ exists (ls or absence).

Command routing

Check $ARGUMENTS:

help → show help, stop
config → run config flow, stop
reset → delete preferences + feedback journal, confirm, stop
feedback → collect thumbs-up/down on the most recent research (see Feedback section), stop
history → list recent research folders with titles and dates, stop
setup or preflight → run the Chrome extension setup/onboarding flow (see Setup section), stop
anything else → run the skill (starts with a preflight check — see Step 0)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
